Home care software built for Mississippi Medicaid EVV.
Mississippi routes EVV through HHAeXchange (EVV Data Aggregator API). First Support Homecare captures every Medicaid visit with GPS clock-in and clock-out, coded reasons and an audit trail, and its HHAeXchange connector is built to the published specification — the certification is completed with your agency as the sponsoring provider, at no cost to you.
AI does the paperwork: faxed referrals become client records and any PDF form becomes fillable in minutes. Your staff checks and signs, so a small office keeps up without another hire.
Mississippi: two phases, then all claims through HHAeXchange
The Mississippi Division of Medicaid (DOM) runs an open hybrid model with HHAeXchange: an agency can use the free HHAeXchange provider portal or connect its existing EVV system. Personal care came first. State plan home health followed in Phase II, which went live in December 2023 after DOM used a good-faith-effort exemption to delay it.
Since then Mississippi has moved billing itself. DOM updated Part 200 of its Administrative Code so that, from December 1, 2025, all claims for EVV-required services are submitted through HHAeXchange. From January 1, 2026 a claims edit suspends any EVV-mandated claim submitted directly in MESA, the state's claims system.
| When | What changed in Mississippi |

| June 2023 | DOM and HHAeXchange kick-off letter to providers. |
| December 2023 | Phase II: EVV for state plan home health goes live on HHAeXchange. |

Bill through the EVV system
Claims for EVV services go to the fiscal agent through HHAeXchange, unless DOM authorizes otherwise in writing.
Free portal or integration
The HHAeXchange provider portal is free; an agency's own system connects to HHAeXchange instead.
Caregivers can be bulk-loaded
Caregivers can be added one at a time or through HHAeXchange's bulk import.
One aggregator: the HHAeXchange Data Aggregator API
Mississippi agencies live inside two sets of rules: Mississippi Division of Medicaid's, and HHAeXchange's. The software was built to both — the state's EVV requirements in the visit record, HHAeXchange's interface in the connector — so the agency does the work once and the aggregator gets it in its own format. Open vendor model.
A REST API with a token
OAuth client credentials, a caregiver record, visits in batches of up to a hundred, and a transactions endpoint that gives each visit its verdict. Members come from the payer's feed; the visit names them by Medicaid ID.
Ten published test cases
HHAeXchange publishes its interface test: authenticate, create and update a caregiver, five visits in a batch, one visit, a missed visit, an edit, a delete, and two that must fail. The software passes all ten against a faithful mock today, and runs them against the real implementation environment with one command.
Edits and missed visits carry codes
A corrected time carries the state's edit reason and action codes; a cancelled scheduled visit can be reported as a missed visit with its own codes.
Everything HHAeXchange requires is the same in every HHAeXchange state - the element-by-element requirements, the onboarding steps and the common questions are on one page. How HHAeXchange EVV works.

Questions Mississippi agencies ask
Can a Mississippi agency bill EVV services directly in MESA?
No. Since December 1, 2025 EVV claims go through HHAeXchange, and from January 1, 2026 a direct MESA claim for an EVV-mandated service is suspended.
When did home health EVV start in Mississippi?
December 2023, as Phase II on HHAeXchange, after a good-faith-effort exemption.
Which Mississippi programs does this cover?
Personal care under the waivers, home health, and the MSCAN and CHIP plans — every service Mississippi Division of Medicaid requires EVV for. HHAeXchange EDI/API integration. Since December 1, 2025 all EVV claims must be submitted through HHAeXchange; edit 712 (from January 1, 2026) suspends direct MESA claims.
Is there a free trial for Mississippi agencies?
Yes. Mississippi agencies that bill Medicaid and sign up by December 31, 2026 get 90 days free with no limit on clients: scheduling, the caregiver EVV app, documents, billing and the family portal. AI features are not part of the trial. Private-pay-only agencies get 15 days.
